MACHINE FOR SAWING WOODl SPECIFICATION forming part of Letters Patent No. 738,453, dated September 8, 1903.

Application filed December 20,1902. Serial No. 135,968. (No model.)

T0 all whom it ntfty concern:

Be it known that L ALvAH S. KENDALL, a citizen of the United States of America, and a resident of Yarmouth, county of Cumberland, State of Maine, have invented certain new and useful Improvements in Machines for Sawing Wood, of which the following is a specification.

My invention relates to a machine for sawing wood and adapted to be operated by hand.

The operation of sawing wood with the use ofthe ordinary saw-horse and bucksaw is a tedious one; and the object ot' my invention is to substitute for those primitive tools a machine capable of being operated by hand with more ease and more efficiency.

The machine consists generally oE a fixed frame having a series of horizontal sliding frames with depending hangers at their ends forming guides for the saw-frames, which are adapted to slide up and down in said hangers. A lever is provided for reciprocating the frames, a lever for automatically lifting the saw-frames at the hack extremity of the stroke, and a saw-horse and holding-lever are provided to hold the stick of wood while it is being sawed.

l illustrate my invention by means of the accompanying drawings, in which- Figure 1 is a partial plan of the machine, showing one of its panels or divisions complete. Fig. 2 is a side elevation, and Fig. 3 is an end elevation.

A represents a fixed frame of suitable size divided laterally, as here shown,into th ree distinct panels or divisions, each panel having in its upper part a pair of guides or ways b', in which slide the horizontal frames B, designed to carry the saws. The saw-frames d, three in number, as here shown, are secured to vertical sliding blocks c at their ends, and these blocks c are adapted to slide in vertical hangers or guides l), dependingfrom the ends of the sliding frames B. The lower ends of the hangers are braced by bars b2, connecting their ends. The saw thus moves horizontally with the frame B, and it is free to slide vertically in the hangers b. The movable frames B are reciprocated by a vertical lever G, pivoted at g2 tothe floor and having several arms connected by a common handle gS on top. The connection from the operating-lever G to the hanger l) is made by two links g, each pivoted by one end tothe hanger l, while the opposite ends are pivoted to the extremities of a lever q', which is pivoted centrally to the operating-lever G. Means are provided for raising the saws at the rear end ofthe stroke to admit of a new stick being placed on the saw-horse c, and for this purposeI employ a bent levert, (shown in Figs. l and 2,) pivoted to a hangerj, the upper end of the hanger j being pivoted by means of a rod j' to the frame B. One end of the lever `iy is connected with the saw-frame by means of a link al' and the other end rests normally against the stop i2, which is secured to the hanger I). When the frame is in its extreme rear position, the end of the lever i'. strikes against a stop 3, Fig. 2, which causes the end of the lever to tilt down and the saw to be raised to its highest position, in which position a new stick may be inserted. The stick of wood is placed on the horse e and held in place by a lever f, pivoted to the frame and having a recess in its lower edge, so situated to embrace the stick of wood. The free end of the lever projects upward far enough to be grasped by the hand and lifted at the front of the machine.

I have here shown three saws, so that the stick of wood will be sawed into fonr pieces; but it is evident that the machine may be made with two saws or any desired number.

The operation of the machine is evident from its construction. When the lever G is drawn back to its rear position, the saws are lifted up as explained and a stick of wood is inserted. As the lever is pushed forward and reciprocated to its normal extent, the saws cut through the Wood easily, the weight ofthe saw-frames forcing them to cut at about the right speed. When they have made their cut, the lever t brings up against the stop t2, and the saws are prevented from descending further. The operating-lever gives a considerable leverage, so that the motion of the machine is easy.

I claim- 1. In a machine for sawing wood, the combination of a stationary frame, horizontal guides thereon, a sliding frame adapted to slide in said guides, Vertical hangers depending from the ends of said sliding frame, a sawframe adapted to slide in said hangers, held by said frame, links pivoted to said hangers, an operating-lever, a connectinglever centrally pivoted to said operating-lever and to the ends of said links.

In a machine for sawing wood, the combination of a stationary frame, horizontal guides thereon, a sliding frame adapted to slide in said guides, vertical hangers depending from the ends of said sliding frame, a sawfrarne adapted to slide vertically in said hangers, a saw held by said frame, a lever for a saw l reciprocating said sliding frame, a 1iftingle ver for lifting said saw pivoted between its ends, a link connecting one end of said lever 1 with said saw and a guide adapted t0 strike and depress the opposite end of said lever.

In witness whereof I have hereunto set my hand at Portland, Maine, this 15th day of December, 1902.
